As the low threshold of LED flexible strips production, the number of its manufacturers is large. The quality varies due to a lot of factors, such as temperature control, LED chip quality, FPC, and so on. It is easy for experienced people to identify quality. Here we teach you how to distinguish high-quality LED strips from poor ones.
1. Examine the solder connection
Formal LED strip manufactures apply high-speed automatic computer-aided SMT process. The solder points of strips used this complicated product process are smoother than those of inferior ones, and solders are evenly distributed. They are in arc shape, stretching from FPC pads to LED electrodes, while the low-quality ones are of unevenly distributed, circle shaped, containing a soldering feet.
2. Examine the FPC
FPC has two types, general copper and rolled copper respectively. The general copper panels can be seen a little embossed, if you look carefully, you will find it from where the solder and FPC connected. Instead, the rolled coppers are combined together, flexible enough to be able to be bended, and never have phenomenon of solder drop. Other conditions when the solder drop can be like high temperature in maintain process.
3. Examine whether the surface of LED strip is clean
If the LED strips apply SMT product technology, the surface is fairly clean without any impurity and stains, while poor ones using manual welding can been seen the trace, leaving some dirty flux and dross.
4. The package
Formal manufactures apply anti-static package, generally, 5 meters a roll or 10 meters a roll. The LED strips are well sealed in an anti-static and moistureproof bag, while the fake ones usually aren’t in order to save cost.
5. Check the label
Formally, the labels should be originally printed on the package bag, and the reel. While the small-scale workshop might just attach the printed labels, and the specifications have not universal standard.
6. Check the accessories
Formal manufacturers will supply the manual and the product specifications, and specific connectors. They come with the LED strips in the same package bag. When you find yours don’t contain these, it is very possible that they come from informal workshop.
